Hi,

2015-09-28 Thread Victor Olaya

When you say sample models you mean the ones in the online github
collection? That repo needs a bit of love, i guess... Anita proposed
separating them in folders indicating which version they work on. It's
a good idea, but I have to find some time to implement it and curate
the collection of scripts and models a bit...

Seems it calls uniqueValues so if that takes a long time it will block.
Depends on the provider I guess.

 Have you verified that is doesn't?  Because that's what it used to do.

Of course.  LIMIT 10 probably is meant for the postgres provider - and that's
what it does already.  The spatialite provider does too.   The oracle provider
limits with rownum and mssql uses top.  So unless there's something
preventing the provider's uniqueValues to kick in, it's already there.

Hey,

Yeah I'm thinking it might just be slow for something like shapefile where
is there no index on that column and it has to get each value to find
the unique
ones.  I'm not looking at the code, just guessing.

I found it rather slow for large PostGIS tables.

As slow as

SELECT DISTINCT attribute FROM table ORDER BY attribute LIMIT 10

?

Re: [Qgis-developer] Sample

2014-07-14 Thread Giovanni Manghi

 In several dialog (e.g. in experssions) there is a button to show only 10 
 values of a
 field. I assumed this was a simple and quick way to inspect the kind of data 
 present.
 In current master, however, clicking on this for a large table freezes QGIS, 
 so I
 interpret this as an attempt to load all of a table.
 Is this correct? In case, I think it should be changed.


for large table it always took a lot (too much), if I'm not wrong it
shouldn't be new in master...
